Groups within groups in RDBMS Realm

I can see how the supplied RDBMS Realm schema supports groups that contain
groups: you simply store a group name as the gm_member field in the
groupmembers table.
Does weblogic or the RDBMS Realm implementation in particular provide any
special support for the concept of nested groups? What I mean is, I want to
make a call like isUserInGroup(String userName, String groupName) and get
back true if the user is either in the specified group or is in some group
that is nested inside of the specified group.
I can write my own little routine to recursively expand the groupmembers and
determine if the user is contained in the specified group, but I wonder if
that is reinventing the wheel.
Thanks!

Thanks for the helpful response, Terry! That was exactly the info I needed.

RDBMSGroup's isMember method is inherited from the FlatGroup class, theAPI
of which is athttp://www.weblogic.com/docs51/classdocs/javadocs/index.html.
I quote
isMember
public boolean isMember(java.security.Principal member)
Returns true if the passed principal is a member of the group. This method
does a recursive search, so if a principal belongs to a group which is a
member of this group, true is returned.
So it looks like somebody already thought of that 'wheel' thing you were
talking about, and you don't have to bother

Disscuss of using RDBMS Realm

Hi,
Now maybe eveyone knows that the RDBMS Realm provided by weblogic 6.0 isn't production
ready, and miss some functions, for examples, change password, or add group no.
It is suprised for me that weblogic didn't support these basic functions of RDBMSRealm
and didn't provide suitable documentation for implementing this RDBMS Realm.
So I ask for help that if everyone know how to implement one function: changeCredential.
I know the weblogic.management.configuration.Uer object has this method (User.changeCredential(oldPass,
newPass)). I know I have to provide one additional database schema for updating
user password. I know I should add a method in the RDBMSDelegate and RDBMSRealm
classes. But I don't the suitable method signature, and couldn't find internal
method call when the user click the "change" button changing password in the Console.
Thank you very much for any idea or help. Also I'd like to deeply discuss other
security issues.
Is any project use the RDBMS realm?
By the way, if anyone try to directly update the database tables as a means to
implement this issues. I have tried this approach, and it seems work fine except
for some catching delay. Can anyone tell me if this is an effective method?
Thx

This RDBMS Realm issue is really bother me too. I was wondering if anyone use the
RDBMS Realm for production. it is difficult to find what the architecture the
RealmMBean object and RealmManager is. Any idea let me know. Good luck.

Refreshing the RDBMS Realm

I am using the RDBMS Realm that comes with Weblogic 6.0.
We have created ejbs to create and insert our users and group members into
the
tables that the RDBMS Realm reads from .
The problem is occasiounly the caching realm gets out of date. When a user
tries
to access a secured resource the attempts fails. After a few more attempts
the
cache will refresh itself and the access works fine.
When I make changes to my user data how can I programmatically tell the
caching
realm to refresh itself. (The refresh through the console will not help me
here).
...Or should I re-think the way I am creating and updating user data, i.e.
should I
only be doing this through the Realm class?
Thanks

Is RDBMS Realm industrial-strength?

I can see that several people are using RDBMS Realm, which started out as an
example. Is the version shipped with WLS 6.0 reliable and robust? Is it
suitable for a commercial application?

The RDBMS Realm shipped with WLS is a sample.
It is not industrial strength. For example,
the schema is string based and pretty slow.
Also, it doesn't support adding new groups or
acls via the console.

WL51: Custom RDBMS realm interctions with CachingRealm

I think I partially understand the interactions between a CachingRealm and a
custom RDBMS realm (extending from ManageableRealm->AbstractListableRealm).
One thing that confuses me is how to deal with FlatGroups that contain other
groups.
Suppose I use the first constructor of FlatGroup which defers the loading of
members until a method is invoked. When my root group, "everyone" (of which
all other groups ultimately belong to), is called to test membership of a
user, each level in the group tree will be successively loaded since the
members weren't pre-loaded. This sounds like it could be terribly slow,
depending on the depth and width of the group tree.
One optimization being considered is to pre-load each group with its
immediate members. As each child group is added to its parent, it would
recursively be adding its children. Thus, "everyone" would have a full tree
of groups inside of it. However, havign been ecplitily loaded by the custom
realm, they weren't pulled through the cache. The entire tree is present,
but not accessible except through the "everyone" group.
Is there a way to load these groups into the cache pro-actively so that the
loading of a group and its children can be optimized (perhaps even using a
connect by, if not using at least a single database call)?
Regards,
Brian.

Problem creating user in RDBMS realm Using com.bea.wlpi.rdbmsrealm.RDBMSRealm

Hi,
I am currently using WLI 2.0 SP2 installation. Here is a very unusual thing I
noticed. Can somebody tell me what is going on ???
1 : I have set up the security realm as indicated in the config.xml file. As far
as I understand, the caching realm entry has attribute pointing to the wlpiRDBMSRealm,
which is a RDBMS implementation from the WLI 2.0 SP2 distribution.
2: I start the server, open the WLS console, and create a new user through the
console. I get no error message and it seems to work fine. ( I also click on the
save it to database link, and it returns with msg that cache is refreshed ).
3: I see an entry in the fileRealm.properties file, but no record is inserted
in the WLSUSER table in the database.
Since the RDBMS realm (from WLI distribution) is defined as basic
realm implementation, should it not insert entry into the database, instead of
the file realm.
Is this a general problem ( any RDBMS realm ) or is it specific to the WLI ?
Is there anything that I have not configured here that is causing this behavior
Is it just refreshing the cache instead of inserting record in DB ?
Why should it insert entry into fileRealm.properties ?
Thanks,

After this I get a very unusual error, which seems to be comming

WLPI does not initialize) ....

RDBMS Realm Schema Properties - newbie looking for some general info

I am new to the world of WL Security Realms. I am trying to better
understand what is involved in setting up a RDBMS Security Realm and
speficially the Schema Properties within that security realm.
The situation that I am trying to solve right now is that I want to
provide authentication for a given application using a "user list"
from another DB that our application will have access to via JDBC.
First off, would using the RDBMS security realm allow me to do
something along these lines - ie access a "user list" from another DB?
If YES, then what sort of things would have to be done from the
schema properties standpoint in order to make this possible?
Note that the other DB will also be an Oracle instance managed by
WebLogic, the same as with our application, if it makes a difference
in any way.
Thanks for the help.

You need to configure the schema so that it fits in with your database
getGroupMembers=SELECT GM_GROUP, GM_MEMBER from groupmembers WHERE GM_GROUP
= ?
deleteGroup2=DELETE FROM aclentries WHERE A_PRINCIPAL = ?
deleteGroup1=DELETE FROM groupmembers WHERE GM_GROUP = ?
addGroupMember=INSERT INTO groupmembers VALUES ( ? , ? )
getUser=SELECT U_NAME, U_PASSWORD FROM users WHERE U_NAME = ?
getPermission=SELECT DISTINCT A_PERMISSION FROM aclentries WHERE
A_PERMISSION = ?
deleteUser3=DELETE FROM aclentries WHERE A_PRINCIPAL = ?
deleteUser2=DELETE FROM groupmembers WHERE GM_MEMBER = ?
getGroupNewStatement=true
deleteUser1=DELETE FROM users WHERE U_NAME = ?
getAcls=SELECT A_NAME, A_PRINCIPAL, A_PERMISSION FROM aclentries ORDER BY
A_NAME, A_PRINCIPAL

Creating New Users for RDBMS realm

I am currently creating new users in the RDBMS realm
by an EJB that will insert into the "Users" table. Is this
the correct way to create users or should I be calling
methods on classes in examples.security.RDBMSRealm?
Thanks
Bill.

Thanks a lot for the guideline.
I can able to create multiple users using Import option of the user administration but i have one more question regarding the same.
What about the password setting of these newly created users. Or can the set the password field in test file?? Because when we export the user, it is not showing any Password field.
Thanks & Regards,
Prashant

[Fwd: Re: rdbms realm and connection pool]

Hi,
One reason why I would like to use the connection pool for the RDBMS
realm is because there is the retry machanism built into the connection
pool. With this retry, I don't need to re-start WebLogic if the DB
server is somehow re-started. With the current implementation, all the
connections maintained by the realm will become invalid if the DB server
has been restarted independently.

I believe not- the realm restricts access to connection pools to those
who
are allowed it, so if the realm needs the connection pool to start up,
and
you can't open the connection pool without the realm then you have a bit
of
a no-chicken and no-egg situation, which is I believe one of the reasons
why
there is no use of connection pools, ejbs, jndi, servlets etc. in the
realm
(along with other reasons, like why would it be provided with a servlet)
The delegate pool acts somewhat similarly to a connection pool, and can
even
use the same database, so I'm not sure what the advantage would be

the connection pool for Database.Is there any that i can point my rdbmsrealm to use
the connection pool for Database instead
Thanks in advance

I believe not- the realm restricts access to connection pools to those who
are allowed it, so if the realm needs the connection pool to start up, and
you can't open the connection pool without the realm then you have a bit of
a no-chicken and no-egg situation, which is I believe one of the reasons why
there is no use of connection pools, ejbs, jndi, servlets etc. in the realm
(along with other reasons, like why would it be provided with a servlet)
The delegate pool acts somewhat similarly to a connection pool, and can even
use the same database, so I'm not sure what the advantage would be

Your syntax looks right so it migth be something else. Could you please post the full example and I'll try it out here.<HR></BLOCKQUOTE>
Sure:
<?xml version = '1.0' standalone = 'yes'?>
<SimpleUser>
<UserName>eclark</UserName>
<Password>ifs</Password>
<DistinguishedNameSuffix>.ambiguity.com</DistinguishedNameSuffix>
<AdminEnabled>false</AdminEnabled>
<HomeFolderRoot>/home</HomeFolderRoot>
<EmailAddressSuffix>@ambiguity.com</EmailAddressSuffix>
<PrimaryUserProfileAcl refType="name">Private</PrimaryUserProfileAcl>
</SimpleUser>
Without the PrimaryUserProfileAcl-Tag, the example works fine and the user is created; but when including the tag, I get the 21000-Error. Our iFS-version is 1.0.8, maybe it's a bug that is fixed in version 1.1?

I am using the Rdbms Realm to control the access to my servlets.
Does anyone know how can I lock a user when he reach the maximum numbers of

You'll need to customise the RDBMS realm so that it keeps track of
this information for you.

Example of RDBMS Realm

Hi,
I have just started out with EJB & weblogic security. I want to make a RDBMS realm in weblogic that connects to oracle dBase. Since I am new to security, I was wondering if anyone out there knew what fields would be added to a table that manages user?. Also how does a table manage ACLs? And last but not least, I noticed that when I was creating a RDBMS realm in weblogic console there is a tab that mentions that I have to write schema properties...what is this and what do I place in it. I have read all of the weblogic docs and there is nothing that addresses theses questions. I would really appreciate any help I can get.
Thank you,
Jay.
P.S I am using weblogic 6.0 with sp1

Is this a continuation of http://forum.java.sun.com/thread.jsp?forum=60&thread=159878
It sure looks like it.
Have you read this weblogic doc http://e-docs.bea.com/wls/docs61/adminguide/cnfgsec.html#1052867
